STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 646,440, dated April 3, 1900.

Application filed September 27,1899. Serial No. 731,802. (No model.)

.To all whom it may concern:

Be it known that I, SOLOMON METER LEvY, a citizen of theUnited States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Stop and Taste Cocks; and I do declare that the following is a full, clear, and exact description of the in vention, which will enable others skilled in the art to which it appertains to make and use the same.

Hy invention relates to what are known as interchangeable or right and left stop and waste cocks, and the object of the invention is to provide a simple and reliable construction of waste-cock which is equally well adapted to right and left positions in service and in which the mere inversion of the handle is the only change necessary to bring the plug to proper wasting position, if not found so in the other position, all substantially as shown and described,an d particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan elevation of a setting in which the cock is setsay in a right position; and Fig. 2 is a like elevation in which the cock is in a left position, or inverse to that shown in Fig. l,I the retaining -screw head being wholly broken awayin Fig. l, and partly in Fig. 2. Fig. 3v is a cross-section on line 2 2, Fig. l, which discloses a plan of the plug, partly sectioned, to show the waste and regular channels for the water in both plug and barrel or casing.' Fig. 4 is a vertical central sectional elevation of the parts seen in Fig. l in the plane of the handle and bisecting the plug on the line of its waste-outlet, as hereinafter fully described. Fig. 5 is a perspective view of the handle alone. Fig. 6 is a perspective elevation of the portion of the barrel and plug with which the handle is more especially associated.

A represents the body or shell of the cock, having the usual waste-hole 2, and B is the plug, having also the usual waste-hole 3.

C is the handle, which fits in this instance upon the rectangular shank or extremity 4 of the plug, but it might be secured thereto or therein in any equivalent Way, the construction and purpose of the invention only demanding that it he conveniently detachable and invertible as to position, thereby Y adapting it to right and left hand work as required. 5 5

The body or shell A is provided with a single stud or small post or projection 5, placed in this instance directly opposite the wasteoutlet 2 on what may be termed the side of the body and bringing the stud in a measure 6o between the square shank 4 and the wasteoutlet 2. However, the stud might be on the opposite side from the waste-outlet, if pre ferred.

Another preferred feature of construction is the shape of theshank 4, which has the form ot' a parallelogram or rectangle rather than a square, although a square could be used, if desired. The special advantage of the present shape is that it harmonizes with 7o my further idea of always making the change of handle if it be found .to be out of position when it is parallel with the body and the pipe D, and so the long sides of the shank are made to run with the line of the handle. It follows inevitably in that case, if by mishap the plug be placed wrong in the body when it is set up, that the inversion of the handle from the full-line position in Fig. l to the full-line position in Fig. 2 will right the plug and 8o bring its exhaust in the right relation for service. The same is true if the handle were down instead of up originally or the pipe were horizontal instead of vertical. Then to exhaust it is only necessary in either case to give the handle a quarter-turn to right angles, as shown in dotted lines. For further convenience in locating the side upon which the exhaust-hole is in the plug I may place a suitable mark, like a smallnotch 6, on the 9o side of the shank 4, and lthis willV enable the plumber when he comes to place the cock to know definitely Whether the parts are in the right relation or not.

The handle C is limited in its operations to a quarter-turn, as described, by the lug 5, which forms the stop in both directions of rotation, engaging the base of the handle itself in one position and the lugr 8 thereon in theother. The handle is confined by the screw roo l0, and the parts are supposed to be assembled and placed in operative relation when sent out into the market. This anticipates the possible difliculty ofy getting the plug in the right relation to the body for waste purposes, and if by mistake it were to be Wrong nothing need be done but to remove and in vert the handle to either position Fig. l or Fig. 2, and that will certainly bring the waste right.

It will be noticed that the lug S on the handle is placed at right angles to the handle and that lthere is a quarter-turn space between them.

1. In stop and waste cooks, the body having a single stop-lug, the plug therein, and a reversible handle xed on the plug and constructed to engage said lug at two points spaced apart equal to a quarter-turn of `the plug, substantially as set forth.

2. The body of the cock having a stopprojection, `a plug in said body and an invertible .handle on said plug having a lug on its head aquarter-turn from the handle, the said stop projection being between the handleand the lug thereon, substantially as described.

The body of the cock and the plug there in having an engagn g portion for thefhandle, in Combination with an invertible handle detachably secured to the plug, the said body having a single lug in the path of the handle to limit its 4rotation, and the handle having two stops on its head a quarter-turn of the plug apart to engage said lug, substantially as described.
